AI Detection

The VTX/VRX digital link supports a real-time AI overlay: objects detected or tracked onboard the drone are transmitted alongside the video and rendered live in your goggles as bounding boxes (with optional labels).

Two onboard sources can drive the overlay:

• Object detection — voxl-tflite-server runs a deep-learning model (e.g. YOLO) on the NPU and boxes every detected object class in view. Display-only: it never influences flight.
• Object tracking — voxl-nano-tracker follows one target selected via an RC switch or voxl-portal (SDK 1.6.3+).

Object tracking is more than a display overlay: combined with VFC AOI yaw tracking, it commands the drone’s yaw to keep the target centered. Read the warnings in the AOI Yaw Tracking guide before enabling it in flight.

The AI Detection Setup Guide covers enabling either source and tuning what gets transmitted and rendered.
